Weird game really.
Our game plan seemed to centre around trying to stay within touching distance for as long as possible and then try and nick something at the end. That's not the worst plan in the world, but it becomes infinitely harder when you gift the opposition a goal after three minutes.
United didn't play particularly well throughout the game but were not really obliged to because we couldn't produce anything in an attacking sense, which is unsurprising given our tactics. We have Ramsey out of position on the right wing, when you have a right winger on the bench, and then Giroud, whose best attribute is heading and general box-play is left isolated without anyone supplying any crosses for him. Amazingly, in the second half, when we actually decided to get the ball in the box, he hit the post and De Gea made a decent save off him.
There were obviously some key refereeing decisions in the game, and none of them went in our favour.
The penalty is an interesting one - it's difficult to say it wasn't a handball because it hits him squarely on the arm, but he is just trying to protect his face from a ball struck from about five yards away. I have seen them given, and I have seen them not given. As a general point, there needs to be a serious look at what is handball in the modern game, because no-one appears to know. For me, it wasn't a penalty.
Mike Dean's biggest error today was the two harsh yellow cards he awarded to Wilshere and Cleverley in the first half. This put him in a very difficult situation when they both committed worse challenges in the second half which were not punished. The problem for me is that if Cleverley is yellow-carded, he absolutely has to be sent off for the second one. It's not even debateable - it's a clear yellow card, and at 1-0, that makes a difference in the game. Add that to the fact you scored from a corner(vaguely) when an offside flag should have been raised before when RVP went through, I think you got away with a couple of calls today.
So basically, correct result, but I felt our tactics let us down massively from minute one, and that combined with not getting much off the officials(although Wilshere correctly went) meant that we had little chance of ever getting anything.
